' In said, drawings 10' designates. a boilerof the horizontal, sectional type generally used for domestic heating purposes, QT'h'e boiler lower or fire-pot section'18; The sveral sec- Theseve'ralsections are respectively'prm v ded -w1tlropenings liavingdoors 11; 12 e -me e- 4 a I iThefad acent faces of the several sections are provided at opposite sides of the boiler ports at one side are secured nipples 15. whi c'h constitute jhesole passage for the ascending currents of heated'water, and witliin tlie ports at the opposite side of theboiler are disposed nipples 16, 17. The nipple 16 serves to connect the top orstea'in dome section 11 with the lntermediate section 12, and has a with fi gi pp e p rts, and within the v relatively short tubular portion mitfgngm;

ly smaller diameter than its nipplefportion,

, extending intosaidintermediate section and terminating adjacent to but free of the base 7 of said intermediatesection. The nipple 17' is located directly 'below'and oin iline' with thegnipple 16" and its tubular portion 16, and serves to connect thejintermediate sec-v tion 12 with the fire-pot section 13'. The said nipple 17' h'as a relatively long tubular v portlon 17 of sliglitly snialler diameter-than its sai d nipple '1 extendingclownwardlybetween the inner and outer walls ofth e fire pot section, and has itslower'free end; terminating ad acen't the base ofth'e fire-pot section.

In order to accommodate the tubular portion 17 a depending froin the nipple'17, the inner wall portion 18 of the fire-pot section is provided with a Vertical, transverselycurved portion 18 which'extends'inwardly into the fire-pot, and the corresponding part of the outer wall portion 19 is provided with a similar portion 19 which extends outwardly beyond the circular contour of the fire-pot section thus providing an enlarged chamber portion 20 of greater internal diameter than i. c

the tubular portion-17 which extends into the same so that said tubular portion shall be protected against the direct heat of the incandescent fuel by the surrounding mass of water.

In order to insure the delivery of dry steam at the nozzle, and to prevent the heated water being immediately drawn into the accelerating means 16, 17, the steam dome is provided with a curved baflie plate 21, above the point where the descending water currents enter the accelerating tubes.

The operation of the boiler will be largely obvious from the foregoing description. It need merely be noted that only two passages are provided for the flow and return of water, viz: the nipples 15 at one side for the ascending currents of heated water, and the accelerating means 16, 16 17, 17 at the opposite side which serve to cause the cooler water to pass from the upper or steam dome section 11 into the nipple 16 and its short tubular portion 16*, and also from the intermediate section 12, entering between the lower end of the short tubular portion 16 and the nipple portion 17 connecting the intermediate sections 12 with the fire-pot section 13, and that the descending water is then carried downwardly by the tubular portion 17 and finally discharged from the lower end of said .tubular portion and into the fireepot section at the base thereof. The water is then caused to pass around said base to the opposite side of the boiler where, as the same becomes again heated, it will rise together with the entrained steam and pass upwardly to the steam dome 11 by way of the nipples 15, and thus maintain a rapid and uniform circulation of water, and a steady water line in the gage glass.

It is to be noted that in order to obtain the most eflicient circulation and acceleration of water flow, the tubular member 17 should be substantially coextensive in length with the height of the fire-pot section, and that sufficient space should be provided between the lower or outlet end of the tubular portion 16 of each nipple 16 of the several sections, and the entrance end of the nipple portion next below in order to induce the flow of the cooler descending water current into the latter-named nipple portions.

Having thus described our said invention, what we claim and desire to secure by Letters Patent is:

1. A horizontal sectional boiler comprising a relatively-deep fire-pot section, and at least one upper section thereon, nipple ports at opposite sides of boiler in the opposing faces of said sections and a nipple secured in the ports at one side of the boiler and constituting the sole passage for the ascending currents of heated water, and water-accelcrating means disposed in the nipple ports at the opposite side of the boiler; said means comprising a nipple portion uniting said upper section with said fire-pot section, and a tubular portion substantially coextensive in length with the height ofsaid fire-pot sec tion extending from said last-named nipple portion into said fire-pot section and having its free end terminating adjacent the base of said fire-pot section, substantially as specified. v
